FLATIRON — A water main break flooded into the 23rd Street subway station Friday causing major delays on the N, Q and R lines, officials said.

The rupture occurred about 10:35 a.m. near the intersection of 23rd Street and Broadway, an FDNY spokesman said.

Water was still flowing down 23rd Street an 90 minutes later.

It's unclear what caused the break.

No one appeared to be injured, the FDNY said.

The R wasn't running between West 57th Street and Whitehall, while the N and Q were out of service between Whitehall and DeKalb Avenue, according to the MTA's website.
